It weighs less than an ounce, but helps the body do many important things, such as grow, regulate energy, and go through <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/development-foyer.html/">sexual development</a>.</p> <h3>What Are Goiters and Thyroid Nodules?</h3> <p>An enlarged thyroid gland can be felt as a lump under the skin at the front of the neck. When it is large enough to see easily, it's called a <strong>goiter</strong>.</p> <p>A <strong>thyroid nodule</strong> is a lump or enlarged area in the thyroid gland. A nodule may simply be swollen tissue, an overgrowth of normal thyroid tissue, or a collection of fluid called a <strong>cyst</strong>. Most thyroid nodules in children are not caused by cancer.</p> <h3>What Causes Goiters?</h3> <p>Goiters can happen due to inflammation of the thyroid gland or when the gland makes too much or too little thyroid hormone. A goiter also can develop with other thyroid problems, such as infections of the thyroid or thyroid cysts, tumors, or <a class="kh_anchor">thyroid cancer</a>. People who don't get enough iodine in their diets also can get an enlarged thyroid. But this is rare in the United States because foods here usually supply enough iodine.</p> <p><img class="center_this" title="A view of the thyroid, a gland below the skin and muscles at the front of the neck, as described in the article." src="https://kidshealth.org/EN/images/illustrations/thyroid_a_enIL.jpg" alt="A view of the thyroid, a gland below the skin and muscles at the front of the neck, as described in the article." /></p> <p>Kids can be born with a goiter or develop one later in life. A goiter that's present at birth is called a <strong>congenital goiter</strong>. These can be caused by:</p> <ul> <li>a <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/about-genetics.html/">genetic</a> disease that prevents the baby from producing thyroid hormone properly</li> <li>thyroid issues in the mother during pregnancy</li> <li>an expectant mother taking medicines or other substances that affect the baby's thyroid</li> <li>the child being born without half of the thyroid, causing the remaining half to get bigger</li> </ul> <p>A goiter that develops later is called an <strong>acquired goiter</strong>. In the United States, most acquired goiters are caused by:</p> <p><strong><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hypothyroidism.html/">Hashimoto's thyroiditis</a>:</strong> The <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/immune.html/">immune system</a> attacks the thyroid, making it swell. Sometimes this swelling can be dramatic and even look like a growth. Over time, the thyroid can become so damaged that it can't make enough thyroid hormone. In that case, a person might need to take a thyroid hormone.</p> <p><strong><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hyperthyroidism.html/">Graves' disease</a>:</strong> This is the most common cause of a goiter with high thyroid hormone levels in kids, and the top cause of <strong>hyperthyroidism</strong> in teen girls. The immune system attacks parts of the thyroid gland, making it swell and produce too much thyroid hormone. It also can cause inflammation and swelling around the eyes.</p> <p><strong>Colloid goiter (also called the "adolescent goiter"):</strong> The thyroid sometimes grows a lot during <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/understanding-puberty.html/">puberty</a>, and can look abnormally large. This is not associated with any thyroid hormone problems. The thyroid works normally and often gets smaller over time with no treatment.</p> <p><strong>Viral or bacterial infections:</strong> Infections can cause inflammation and enlargement of the thyroid. These goiters are often painful.</p> <h3>What Causes Thyroid Nodules?</h3> <p>The most common cause of a thyroid nodule in kids is actually a "pseudonodule" or "fake nodule." This is when inflammation of the gland (due to an infection, Hashimoto's thyroiditis, or Graves' disease) makes the thyroid swell in one place. This inflammation might look like a nodule, but there isn't really any nodule at all.</p> <p>The next most common type of thyroid nodule is a cyst, which usually happens when normal fluid pockets in the thyroid get bigger. These types of nodules are always benign (are not cancers), but may continue to grow over time.</p> <p>Thyroid nodules that are due to growths (tumors) are common in adults but less common in kids. Most thyroid nodules are benign and doctors don't always know why they happen.</p> <p>Kids and teens with Hashimoto's thyroiditis have a higher risk of thyroid nodules. As with goiters, a lack of iodine can cause thyroid nodules.</p> <h3>What Are the Signs &amp; Symptoms of Goiters and Thyroid Nodules?</h3> <p>A goiter is most often spotted because it's in the very front of the neck and moves up and down when a person swallows. People with a goiter might have the sensation that food is stuck in the throat, especially when they lie down or sleep on their backs.</p> <p>But goiters often grow very slowly over months and years before being noticed. It can be hard even for parents who pay close attention to notice the change early.</p> <p>Sometimes a nodule can appear in a healthy gland. It may feel like a lump in the throat, or cause tenderness or pain in the front of the neck. A large nodule might be visible at the front of the neck. Some kids with thyroid nodules have pain in the front of the neck or feel like they have a lump in the throat.</p> <h3>How Are Goiters and Thyroid Nodules Diagnosed?</h3> <p>Goiters and thyroid nodules are often found by families and doctors by looking at and touching the neck. Lab tests and a thyroid ultrasound can give doctors a good idea of what's going on. If a thyroid nodule is found, extra testing is sometimes needed.</p> <p>A fine-needle <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/biopsy.html/">biopsy</a> might be done to see whether a nodule is <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/cancer.html/">cancerous</a>. During the biopsy, the doctor inserts a thin needle through the skin into the thyroid nodule (the skin is numbed with medicine first). Through the needle, the doctor takes a sample of tissue or some fluid from a cyst. The tissue or fluid is then sent to a lab. In some cases, the nodule might have to be surgically removed for more a detailed examination.</p> <p>Some thyroid nodules make too much hormone and so another test, a <strong>thyroid scan</strong>, might be done. For this test, a person swallows a pill containing a small amount of radioactive iodine or another radioactive substance. The thyroid absorbs the radioactive substance. Then a special camera measures where the radioactive substance is taken up by the thyroid gland. This gives the doctor a better picture of the location, size, and type of thyroid nodule.</p> <h3>How Are Goiters Treated?</h3> <p>Depending on the test results, a goiter might not need to be treated. If it does, treating the thyroid disease causing the goiter usually will decrease or control the enlargement.</p> <p>Surgery might be needed if the thyroid keeps getting bigger even with treatment and causes discomfort or a very large lump in the neck.</p> <h3>How Are Thyroid Nodules Treated?</h3> <p>Thyroid nodules don't always need treatment. Many nodules cause no symptoms and may even get smaller over time.</p> <p>Thyroid nodules may need treatment if they grow or cause symptoms, or if there is concern that it could be a cancer. Surgery is the preferred treatment for thyroid nodules in children. This might involve removing part of or all the thyroid gland.</p> <p>If needed, surgery is done in a hospital under <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/anesthesia-types.html/">general anesthesia</a>, so the child is asleep and feels nothing. If only part of the thyroid is removed and the rest of the gland is healthy, a child may not need to take a thyroid hormone after surgery. If the rest of the gland isn't healthy or if the whole thyroid is removed, the child will need to take a thyroid hormone.</p> <p>Thyroid cancer is relatively uncommon. When it does happen, it is very treatable. Most thyroid cancers can be cured or controlled with treatment.</p> <h3>When Should I Call the Doctor?</h3> <p>Call your child's doctor if:</p> <ul class="kh_longline_list"> <li>The nodule gets bigger.</li> <li>Your child has increased pain or tenderness.</li> <li>Your child has trouble swallowing.</li> <li>Your child has unexplained <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hoarseness.html/">hoarseness</a>.</li> </ul>Bocio y nódulos tiroideosUna tiroides agrandada se puede notar como un bulto debajo de la piel en la parte anterior del cuello.

CAT Scan: NeckA neck CAT scan can detect signs of disease in the throat and surrounding areas. Doctors may order one to detect abscesses, birth defects, cysts, or tumors.https://kidshealth.org/ws/RadyChildrens/en/parents/scan-neck.html/3900989f-95ab-4590-b08d-ea97a75ff1b9
Hyperthyroidism and Graves’ Disease Hyperthyroidism happens when the thyroid gland sends too much thyroid hormone into the blood. The most common cause of hyperthyroidism is Graves' disease.https://kidshealth.org/ws/RadyChildrens/en/parents/hyperthyroidism.html/95857eb0-5b82-4454-b9c9-418e19008b30
Hypothyroidism and Hashimoto’s ThyroiditisAn underactive thyroid makes too little thyroid hormone, causing hypothyroidism. Hashimoto's thyroiditis, which causes most cases of hypothyroidism in kids and teens, is a condition in which the immune system attacks the thyroid.https://kidshealth.org/ws/RadyChildrens/en/parents/hypothyroidism.html/8efef5d8-104a-4baa-878c-a02884d9f4af
Thyroid DiseaseThe thyroid gland makes the hormones that help control metabolism and growth. A thyroid that isn't working properly can cause thyroid disease. https://kidshealth.org/ws/RadyChildrens/en/parents/thyroid-disease.html/84573bd7-3de9-46b0-b1af-0f7a762c5d48
Thyroid TestsThyroid blood tests check thyroid function and can help doctors diagnose thyroid disorders such as hypothyroidism and hyperthyroidism.https://kidshealth.org/ws/RadyChildrens/en/parents/thyroid-tests.html/5dc5d0a7-d45d-4fd2-9cd4-bb534bf1d7b3
